Lucky in Limburg

Three new butterfly species for me in one weekend

For this year my goal is to photograph as much rare butterfly species in Holland as possible. Why? Because I want to have seen them before they go extinct. The sad news is that butterfly numbers in Holland have decreased by 84% since 1890 (CBS, March 2019) and 40% alone since 1992 (Vlinderstichting, March 2018). Last year’s long and extremely dry summer may have given the final push over the brink for some of our country’s remaining species. Climate change, intensive agriculture, pollution and habitat loss are the main contributors to this dramatic decline. I am grateful for the good work of the Dutch Butterfly Association (vlinderstichting.nl) and other NGO’s to counter this trend.

Now back to the good news: the first ones are in the pocket. In late May I travelled to the Dutch province of Zuid-Limburg. As Holland’s most southern province, more or less on the same latitude as Belgium, it has a relatively warm climate in a landscape dominated by chalk hills. These make for a very unique and diverse flora and fauna.

The species I was looking for was the Glanville Fritillary (Melitaea cinxia). The village of Bemelen has a small population and  with great anticipation I climbed the local hill to the place-to-be. Only to encounter a fence and a no access sign….damn! Should have realized this of course. The skies were overcast and nothing was flying around so my chances of seeing one were reduced to zero in a split second. I walked around some more to get the lay of the land but soon accepted the fact that nothing would come of it. I decided to drive a short stretch to an abandoned quarry. It was already around 6pm and the sun finally broke through. I got my lucky break then: the Small Blue (Cupido minimus) appeared out of nothing. An extremely rare butterfly for the Netherlands that I did not expect to see. This quarry was close to my hotel so I decided to call it a day and return the next day.

On Sunday, my early-morning visit was first to the Sint Pietersberg to scout for the Dingy Skipper (Erynnis tages). Despite sunshine and just a little wind, I could not find a single one. I can just confirm that their brown camouflage works very well…

Therefore I returned to the quarry and saw my first Glanville Fritillary within minutes. All smiles. I took a step closer….gone. Nowhere to be found and I promised myself not to wander off the path. However, the Small Blues were still around:

I decided to try another location and that proved to be a good decision. On a local chalk hill this fresh Glanville Fritillary decided to pose for me. I finally got what I came for.

The catch of the day was this Wood White (Leptidea sinapsis) that I literally stumpled upon. It flew away a few meters in its characteristic fluttery way, but after a few tries it settled down and I could sneak close enough for this shot.

Three new butterfly species in one weekend: I was very happy with this result and drove home to Amsterdam in a good mood. Let’s see what the rest of the season brings.
